Anatomical terms of muscle

For the muscle of the neck, see Rectus capitis lateralis muscle

The lateral rectus muscle is a muscle in the orbit. It is one of six extraocular muscles that control the movements of the eye (abduction in this case). Its function is to bring the pupil away from the midline of the body.

Structure

See also: Extraocular muscles

The lateral rectus originates at the lateral part of the annulus of Zinn, also known as the annular tendon or common tendinous ring, and inserts into the temporal side of the eyeball. The annulus of Zinn is a tendinous ring that surrounds the optic nerve and serves as the origin for four of the six extraocular muscles, excluding the inferior oblique muscle and superior oblique muscle.

Innervation

It is the only muscle innervated by the abducens nerve, cranial nerve VI.

Function

See also: Eye movement

Clinical significance

A sixth nerve palsy, also known as abducens nerve palsy, is a neurological defect that results from a damaged or impaired abducens nerve. This defect can result in horizontal double vision and reduced lateral movement. Proper function of the lateral rectus is tested clinically by asking the patient to look laterally.
